Imagine this scenario:
Nathan Peterman returns to the starting lineup, wins meaningful games during the playoffs battle, gets the Bills into the playoffs and wins at least one playoff game.
The once 5-0 Chiefs, who traded its 2018 1st round pick loses more games and fail to make the playoffs.
The Bills coaches would probably almost certainly give Peterman their vote of confidence heading into the next season. Bills are probably selecting just before pick 20 and don't have to use a draft pick on QB.
If this plays out, the Bills won the draft-day trade hands down. Still a big believer that Patrick Mahomes will prove to have been picked several picks too early.
